In my opinion Ogawa Choraku lineage is the second most important Raku - lineage after the Raku Kichizaemons.
Ogawa Choraku was trained by Kenyu from the Raku family in late 19th century and opened his own kiln neat Kyoto in early 20th century with deep ties to Urasenke tea school. His son Ogawa Choraku 2nd was closely trained by him and made a succeeding life-long career as a potter.
The teabowl I am selling is a succulent example of Choraku's red-black Raku from the later part of his career. The tube form, slightly more wider from the bottom makes it very good to hold. The rim has strong wavy form with five peaks. The carvings on the interior bottom and around the kodai are definately worth a mention. Texture is beautifully fired, black and red with the white ash build-ups. In close-up photos you can see some shades of blue but those are reflections.
I assume the chawan is from 1960s or 1970s. It's marked with the artist seal and comes with the original signed wooden box.
The condition is very good. There is no damage, no detoration or flaking of glaze and has only very small signs of age or use. The original wooden box has signs of age such as dents or cracking.
